Question: The standard reaction enthalpy for the decomposition of CaCI2NH3(s) into CaCl2 (s) and NH3 (g) is nearly constant at +78 k] rnol-1 between 350 K

The standard reaction enthalpy for the decomposition of CaCI2•NH3(s) into CaCl2 (s) and NH3 (g) is nearly constant at +78 k] rnol-1 between 350 K and 470 K. The equilibrium pressure of NH3 in the presence ofCaCI2•NH3 is 1.71 kPa at 400 K. Find an expression for the temperature dependence of "'rG" in the same range.
